A. The experiment is not a binomial experiment because there is not a fixed number of drawings.
B. The experiment is not a binomial experiment because the probability of choosing a green marble is the same for each drawing.
C. The experiment is not a binomial experiment because the probability of choosing a green marble is not the same fo each drawing.
D. The experiment is not a binomial experiment because there are only two possible outcomes for each drawing.

The experiment is not a binomial experiment because the probability of choosing a green marble is not same for each drawing

What is binomial experiment ?

An experiment consisting of a fixed number of independent trials each with two possible outcomes, success and failure .

The experiment is not a binomial experiment because the probability of choosing a green marble is not the same for each as after drawing the marble from hat , he is laying the marble aside and not putting it back into the hat which altered the probability every time because total number of marbles are decreasing after every turn of drawing.

hence , correct answer is
